SHORT COMMUNICATIONS. ELECTRIC Eel at the Adelaide Gallery.I feel persuaded that your readers will be interested in hearing that the Gymnotus I described in my letter to you, is still living and thriving. Kept in a room daily frequented by multitudes of persons, with only a borrowed light from a skylight, and never feeling the direct rays of the sun; confined in a vessel in which it cannot now stretch itself out at full length; kept warm by water artificially heated ; and fed with fish not indigenous to the country it inhabits ;—what must be the power of adaptation to external circumstances possessed by the animal which admits of its not only living, but even growing and increasing in strength, under such a total change of habits, food and climate !

I believe you remember that when we first began to experiment on its electrical powers, we could only produce those phenomena which depend on the tension of the electricity, as the spark, &c., by employing secondary currents; now, on the contrary, we have discarded Henry's coil from our apparatus, and invariably succeed, not only in obtaining a direct spark, but even the deflagration of gold leaves, these leaves being mutually attracted from a sensible distance and burning on coming into contact: if this arises partly from increased skill in our mode of manipulation, it must also be assigned in an equal degree to increased power in the eel.

Nevertheless, convinced as I am that not even the vital power of this animal can long withstand so total a change

in its natural habits, I should be very glad to transfer it to some Institution, where, while it could enjoy fresher air and direct light, it would meet with attention to temperature and cleanliness equal to what it has had from us; and in that case I see no reason why it might not be kept alive for years.Thomas Bradley, Director:- Royal Gallery of Practical Science, Adelaide Street, Oct. 23, 1839. *

Young of Loxia curvirostra, Temm. ( Cross-bill.)-On the 10th of July, 1839, as I was riding under some fir-trees, my attention was attracted by the peculiar note of the Loxia curvirostra ; my stopping to pry too minutely into their actions caused them to change their quarters to an ash tree, where they and their motions were more distinctly discernible, and I could clearly see, and watched for a considerable time the two old ones, in shabby plumage, and four young ones, full two-thirds grown, which appeared very hungry and exceedingly clamorous for food, fluttering their wings, opening their beaks, and incessantly importuning the parent birds for sustenance; thus proving, if additional proof were wanting, that the cross-bills do occasionally build and breed here, although it is probably of rare occurrence, which is not to be accounted for, as so many do remain during that season of the year when all our other birds are engaged in the usual and necessary occupation of reproduction. -Joseph Clarke. -Saffron Walden, Oct. 18th, 1839.

Note on Achatina acicula.Of all the British land shells, the remnants of this species seem to be found in the most singular places. Instances are, I believe, recorded where these shells have been found in Danish coffins, &c. I beg to add another instance of this shell being found in connexion with Danish remains. While carefully examining the tympanum of a skull found at Limbury, a hamlet of Luton, Bedfordshire, in conjunction with old pottery, urns and a key,supposed to be of Danish origin, I was rather surprised to find in addition to the perfect chain of bones, the lower two whorls and a half of a shell, which upon examinination proved to be the remains of Achatina acicula, (Agate shell) a species of rare occurrence at the present time in the vicinity of Luton. How this shell could have found its way into the cavity of the ear I do not pretend to say. I merely bring it forward as another proof of the species having been again discovered in connection with Danish remains.Daniel Cooper, Surgeon, 82, Blackfriars Road, London.

Derivation of the Name of the Adder, (Viper).-Professor Bell in his history of British Reptiles, when giving the etymology of the word adder, as one of the names of the viper, states that it was anciently written Nedre, which he derives from the Saxon Nedre, nether or lower, in allusion to its creeping position ;-a derivation too far-fetched, in my opinion, when there is one much better nearer at hand, viz.Neidr," the ancient British, and also the modern Welch name of the reptile in question. In the plural form it is much more apparent,—“Nadroedd,” (the word is used for the common snake as well as the viper); by only altering the Welsh plural termination for the English one,-Nadrs,—the name is formed at once. The change of neidr into adder is not so bad as what has happened to a companion of it, viz., the change of glein neidr” into “adder claim" or "snakes' claim," the “anguinum ovumof the ancients, the superstitious virtues of which are not yet lost in the estimation of many of the ignorant country people, although it has sunk very much in its dignity, being now chiefly accounted valuable as a cure for wens or glandular swellings of the neck, instead of insuring to its possessor all sublunary prosperity, as it used to do in ancient days. The manner of forming the glein neidr, as preserved by tradition to the present day, and as I have heard it related by several persons, who knew not it had ever been described

by any author, differs but little from the account given by Pliny many centuries ago. The modern version being that it is formed of the saliva of adders upon the body of one of their number, which accounts for the perforation in it. After it is fully formed it must be snatched away by the observer (who must have concealed himself from the observation of the adders); as soon as he has obtained it he must fly with the greatest speed he can possibly exert, until he crosses some stream of water, it matters not how small it be, a running drain or ditch will suffice to stop the pursuers: but if he should be overtaken by the adders, it would be instant death to him, as from their excited state their poison would be doubly powerful. I had one of these articles presented to me some years ago, by a believer in its virtues, in whose family it had been for several generations. It is an irregular, roundish bead, about į of an inch long and 4 of an inch in diameter; the perforation being about of an inch in diameter. The colour is a bright green and the substance apparently glassy, and it is deeply striated longitudinally.James Bladon.-Pontypool.
